As used in this chapter, the finding of a board or council that “cancellation and alternative use will not result in discontiguous patterns of urban development” authorizes, but does not require, the board or council to cancel a contract if it finds that the alternative use will be rural in character and that the alternative use will result within the foreseeable future in a contiguous pattern of development within the relevant subregion. The board or council is not required to find that the alternative use will be immediately contiguous to like development. In rendering its finding, the board or council acts in its own discretion to evaluate the proposed alternative use according to existing and projected conditions within its local jurisdiction.
